My quilty friends, we’ve talked about many things within the pages of this blog. We’ve covered flannel and linen fabric, cotton and poly thread; we’ve even waved goodbye to conventional wadding and ushered in a new era of bamboo, wool, and midnight-shaded batting. But there’s still one material in which we've barely skimmed the surface, even though it’s a very fine surface indeed.
I’m talking about knits, people. Stretchy, squishy, yummy, scrummy, wrap me up in a tight-fabric-burrito-cause-they’re-so-soft – knits. Back on our Quilty Adventure through different substrates, we talked specifically about jersey knit, so be sure to check that out too.
If you follow along with my personal sewing adventures, you may know that I recently started quilting with knits and even designed a pattern that works exceptionally well with it, the Bohemian Garden quilt pattern. Through my experiments and studies, I learned some things that make this substrate an incredibly fun fabric for quilting. So take this journey with me cause knits are wonderfully flexible, so we can be too!
How to Sew with Knits: A Basic Knit Q & A
Q: In two sentences, what’s the difference between knit and regular quilt-weight cotton?
A: Two sentences you say? Oh dear...let me think...OK, the most important takeaway is that your typical quilt-weight cotton is made from two threads being woven together – which means it will fray when you cut it. Knits, however, are created using one continuous yarn being looped back and forth – the result is a fray-free world.
You can see what I'm talking about below. Notice the dark pink fabric on the left has a clear weave and edges that fray. Do you see how the light pink knit on the right has tiny rounded loops as the raw edge? You'll have to look really closely for that. But if you do, you'll notice that even this light-weight knit looks like a knitted sweater...a tiny, mouse-made sweater.
Q: Are Knit and Jersey the same thing?
A: Being new to knits, I started off using the terms “jersey” and “knit” interchangeably. For the most part, you can get away with that and you won’t be wrong. However, if you want to get specific, and technically “correct,” jersey is a type of knit. Knitted fabric without a distinct rib is generically called jersey.
Q: Now that you bring it up, is jersey from New Jersey in the United States?
A: Those of us in the U.S. would like to believe that to be true, however, jersey originated from the Bailiwick of Jersey, a Channel Island off the coast of England. The fabric was commonly used for fishermen’s clothing and was originally a lot heavier than the quilt-o-licious jersey knits we know today.
Q: What should I look for when buying knits for quilting?
A: This is mostly preference, but since I’m the one writing, I’ll give you my preference. Look for fabric with some weight to them. If the store or website is listing weight, shoot for 10 - 12 oz. Knits lighter than that can end up being a little transparent and in turn have more stretch to them. If your fabric shop or favorite online shop does not list weight, look for one that is mostly cotton or labeled cotton interlock.
Q: You just threw in another term! What is interlock?
A: Sorry! So sorry! I didn’t mean to throw new information at you this late in the blog post. I’ll keep it brief. Interlock knit is a wonderful first-timers knit because it’s thicker than your average jersey and doesn’t have the same amount of stretch. It’s made up of two rows of stitches, one directly behind the other – which gives it its thickness and allows it not to curl at the edges. (You know how sometimes your jersey T-shirts can do that?)
In the photo above, the bright chartreuse is a jersey knit and the light blue is an interlock knit. The obvious difference is what the raw edges do – one curls and the other stays nice and flat.
I used a mostly cotton interlock knit to sew my original Bohemian Garden quilt. The Bohemian Garden wholecloth quilt, however, uses two large pieces of jersey knit. See how the edges roll a bit at the binding? (The same Boho Garden quilt pattern includes instructions for both versions.)
Q: I’ve purchased my knit and now I’m ready to sew. I scared.
A: Don’t be scared! Hold my hand. Let’s do this together. If you are using your basic sewing machine, flip your regular straight stitch to either a stretch stitch (looks like a lightning bolt) or a zig-zag stitch. You can use the same thread you always use when piecing a quilt. I like to strap on my walking foot, but as long as you have a foot that’s wide enough for your zig-zag stitch, you’re good.
Ready? Now sew...slow. I mean, not weirdly slow, just sew a bit slower than you normally would. Let your feed dogs do their job and feed the knit through the machine. I almost don’t even want to say it, because it’s not going to happen because you are a great quilter, but try not to stretch the fabric at this point. See? I shouldn’t have said anything. You totally weren’t going to do that anyway!
If your machine only has a straight stitch, don’t count yourself out. There’s this magical stuff called stretch thread that you can get. Load your top and bobbin thread with that, and your straight stitch will remain secure without fear of popping.
One final thought I’d like to leave with you. Knits don’t fray. Yes, yes, I know we covered that already, but I want it to truly sink in. If you’ve ever dreamed of trying appliqué, or even if you are an appliqué master, think about the possibilities if you don’t have to worry about your fabric fraying. The sky's the limit! Now go on and get down with your stretchy self!
Do you have any knit tips? I still learn new things all the time about this substrate, so I'd love to hear from you!
